@vladisld the problem is that if the indicator is changed or there are several complicated ones, is there any way to automatically determine how long need to be loaded earlier?

automatically load extra periods for indicators
I am a newbie for BackTrader. Could you give me some help? I want to know if it is possible to automatically load extra periods for an indicators.
For example, I add a data feed and specify from_data as '2020-01-01'. And I add a indicator MA(10). Is there anyway to load extra periods and make the indicator ready before '2020-01-01'? so, the back testing can be conducted from '2020-01-01' exactly.
